E. coli strains isolated from urine of dogs and cats with urinary tract infections (UTI) and from feces of healthy one's were serotyped, and the serotypes were correlated with uropathogenic virulence factors. The most prevalent O-serotypes, O4 and O6, were isolated from dogs and cats with UTI. In contrast, O11 and O102 strains were the most frequently found from feces of healthy dogs and cats. Most of type O4 and O6 strains possessed such virulence factors as pil, pap, sfa, hly, and cnf1, while most type O11 and O102 strains pil only or pil and aer. All strains of type O75 possessed afaI and aer. K1 antigen was negative in all strains obtained from UTI.
对从患有尿路感染（UTI）的犬猫尿液以及健康犬猫粪便中分离出的大肠杆菌菌株进行血清分型，并将血清型与尿路致病毒力因子相关联。最常见的O血清型O4和O6是从患有UTI的犬猫中分离出来的。相比之下，O11和O102菌株是在健康犬猫粪便中最常发现的。大多数O4和O6型菌株具有菌毛、菌毛相关蛋白、S菌毛抗原、溶血素和细胞毒素坏死因子1等毒力因子，而大多数O11和O102型菌株仅具有菌毛或菌毛和侵袭素。所有O75型菌株都具有afaI和侵袭素。从UTI中获得的所有菌株K1抗原均为阴性。
